3M™ Membrane Switch Spacer Single Coated 7993MP features 3M™ High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 1 mil carrier. This clear PET film provides a smooth, bright appearance, eliminating the need for floodcoat on overlays and keypads. The adhesive withstands repeated switch actuation and forms neat, clean edges for precise slitting and die-cutting.

  • Excellent for graphic overlays and keypads
  • 3 mil single-coated spacer is ideal for withstanding repeated stress of switch actuation
  • 2 mil 3M™ Acrylic Adhesive 200MP delivers excellent shear strength, resists slippage and edge lifting
  • Clear 1 mil polyester film carrier adds brightness, eliminating need for floodcoat
  • Heavy 94# polycoated kraft (PCK) liner delivers improved handling and lay-flat
  • Adhesive resists oozing at slits and die-cuts for faster part processing
  • Liner adds dimensional stability for high-speed rotary die-cutting

A Top Performer Before, During and After Application
Featuring 3M™ High Performance Acrylic Adhesive 200MP, 3M™ Membrane Switch Spacer Single Coated 7993MP is ideal for the stresses of switch actuation over long periods. This single-coated, single-liner membrane switch spacer features a clear 1 mil polyester film carrier which adds brightness and structural strength to exterior surfaces, great for graphic overlays and keypads where floodcoating may otherwise be required. The adhesive is formulated for excellent shear strength – forming a durable bond with plastics and other smooth surfaces with less oozing at the edges. This allows for easier slitting and die-cutting, faster part processing and minimal waste.

The 94# polycoated kraft (PCK) paper liner is heavier than standard liners for improved handling and lay-flat properties. It is designed to cover adhesive consistently for full bonding performance after application. The durable liner resists curling, tunneling and buckling, increase dimensional stability and holds up even under high humidity for efficient storage and processing. Liner design also enables improved rotary die-cutting at high speeds, as well as improved sheet processing.

Recommended Applications

Membrane switch spacers
Switch mounting
Graphic overlays
Circuit layer assembly
Metal dome placement
Lead protection
Die-cut laminations

Resilient and Ready
3M™ Membrane Switch Spacer Single Coated 7993MP is constructed with 2 mil high performance acrylic adhesive that is coated on one side of a 1 mil white polyester film carrier. This membrane switch spacer comes with a 94# moisture-resistant PCK paper liner. Designed to separate switch circuitry until actuation, 3M™ Membrane Switch Spacer Single Coated 7993MP provides excellent high temperature resistance (up to 400°F/204°C short-term heat resistance) as well as chemical and UV resistance.

About 3M™ High Performance Acrylic Adhesive 200MP
3M™ High Performance Acrylic Adhesive 200MP is an industry standard for graphic attachment and general industrial joining applications. It features outstanding adhesion to metal, polycarbonate (PC), ABS and polyester (PET), making it popular across many industries. This adhesive provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot/cold cycles, providing confidence that the switch will perform through difficult environmental conditions and millions of actuations.

The Right Choice for a Range of Applications
With low cost, long life, outstanding environmental performance and eye-catching graphics, membrane switches are found in more and more applications. They range from farm tractors and medical test systems to microwave ovens and fish finders. Whatever the need, 3M has a membrane switch construction suited for the job.

Better Science for Better Adhesives from 3M
Since 1925 when a lab assistant invented masking tape, 3M has been applying science to life – developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each industrial labeling and adhesive product like 3M™ Membrane Switch Spacer Single Coated 7993MP, to help businesses operate faster, better and more efficiently.   Add to cart
